Definitions
- the present invention relates to hinges, and in particular, to hinges that are self-indexing.
- hinges Many different styles and configurations of hinges have been developed over the years.
- the style and configuration of a hinge can depend substantially upon special needs for the hinge. For example, sometimes there is a need or desire for self-indexing.
- self-indexing it is meant that the hinge will hold the pivoting door in a certain position until or unless someone provides sufficient force to move it out of that position. The position discussed is the indexed position.
- the door may be kept in a normal or in an indexed position without the door freely pivoting. Then the door can be indexed to one or more positions.
- Certain hinges also must support heavy doors. Some must work with doors that are difficult to mount to a hinge.
- An example of a heavy and difficult to mount door is a glass panel door, an example of which is a 3/8" to 1/2" glass shower door.
- hinges also must operate in difficult environments.
- An example is a shower door which will be in a very humid environment.
- the hinges will experience substantial humidity and direct contact with water. They also may experience harsh cleaning agents or procedures.
- a hinge that can be advantageously used with glass panel shower doors and provide self or automatic indexing.
- a main pivot pin includes at least one indexing detent parallel to the pivot axis for the hinge.
- a subroller pin is held against lateral movement but is biased against the main pivot pin in alignment with a portion of the pin bearing the detent.
- the main pivot pin rotates with the opening and closing of the shower door.
- the subroller pin is forced into at least a part of the detent. This provides the indexing.
- the above described hinge represented a durable and improved apparatus and method for a self indexing door, especially for glass panel shower doors.
- the position of the detent is adjustable relative to flattened opposite portions of the main pivot pin that matingly fit into receivers in the other half of the hinge so that different indexed positions are possible.
- the flattened portions in the receivers thus keep the detent in a stationary position. Rotation of the door would cause the main pivot pin and detent to rotate relative to the fixed sub roller pin.
- the detent, in operation was always fixed relative to the door.
- Different main roller pins could be manufactured with the detents in different positions to provide different self-indexing positions.
- the present invention is an apparatus and method related to an indexing hinge.
- a mounting base is securable to a supporting structure.
- the supporting structure can be above or below the door but is not necessarily so limited.
- a mounting member is securable to the item to be pivoted.
- a pivot pin having a pivot axis is secured relative to one of the mounting base or the mounting member.
- the pivot pin has an indexing detent along its longitudinal length.
- a biased member is generally fixed in the other of the mounting member and mounting base but biased against the perimeter of the pivot pin.
- the biased member has biased supports relative to the pivot pin so that upon alignment of the detent with the biased member, the biased member at least partially enters the detent to provide an indexed catch or stop. Release from the indexed catch or stop is possible upon the application of sufficient forces to rotate the pivot pin so that the detent moves away from the biased member.
- the method according to the invention includes securing the first member to the perimeter of an item to be pivoted.
- a second member is secured to a supporting structure.
- An indexing detent is formed along the longitudinal axis of a pivot pin positioned between the first and second member.
- a biased member is biased against the pivot pin and at least partially enters the indexing detent when aligned with the biased member, thereby aligning the indexing detent when pivoting the item to be pivoted to an indexed position.
- the mounting member is clamped or secured to a glass panel shower door and the mounting base is secured to the framework surrounding the opening to the shower.
- the hinge can work by clamping to the top and bottom of the shower door with the mounting g members being secured to the floor or stoop of the shower opening and soffits, header or sidelight above the shower door.
- FIG. 1 is a perspective view of a glass panel shower door pivotally secure at the left top and bottom to supporting structure above and below the opening to the shower.
- FIG. 2 is an enlarged isolated perspective view of an indexing hinge according to a preferred embodiment of the invention.
- FIG. 3 is a still further enlarged sectional view taken along line 3--3 of FIG. 2 and including the sectional view of a glass panel shower door to which the indexing hinge is mounted.
- FIG. 3 illustrates the indexing hinge attached to the upper left side of a glass panel shower door and ghost lines indicate pivoting of the shower door in two directions.
- FIG. 4 is similar to FIG. 3 except it illustrates the indexing hinge according to the preferred embodiment of the present invention secured to the center of the glass panel shower door. ghost lines show pivoting in opposite directions of the shower door.
- FIG. 5 is an exploded perspective view of the indexing hinge of FIG. 2.
- FIG. 5A is an enlarged isolated view of a bearing support used in the hinge of FIG. 5.
- FIG. 6 is an enlarged sectional view taken along lines 6--6 of FIG. 2.
- FIG. 6 shows attachment of the indexing hinge to a glass panel shower door and the indexing mechanism of the hinge.
- FIG. 6 shows the door in the indexed position.
- FIG. 7 is similar to FIG. 6 except it shows the glass door and the portion of the indexing hinge secured to the glass door rotated out of the indexed position.
- FIG. 8 is an enlarged view of the portion indicated by line 8--8 in FIG. 7.
- FIG. 9 is an enlarged bottom end view of the main pivot pin and indexing detents of the main pivot pin shown in perspective in FIG. 5 and cross section in FIGS. 6-8.
- FIG. 10 is an enlarged perspective view of an alternative embodiment of a main pivot pin.
- FIG. 11 is similar to FIG. 8 which showing the main pivot pin in FIG. 10 in place in the indexing hinge according to the present invention.
- FIG. 12 is an isolated, partial perspective view of a glass panel shower door and cut out to receive the indexing hinge of FIG. 1.

- FIG. 14 is an alternative embodiment of FIG. 5.
- FIG. 15 is an enlarged perspective view of part 90 of FIG. 14.
- FIG. 16 is an enlarged sectional view similar to FIG. 13 but showing the embodiment of FIGS. 14 and 15.
- the preferred embodiment is discussed relative to a glass shower door, such as is well-known, pivotally secured in the opening to a shower. No mechanical latch or lock or sill need to be used with the door although such is not precluded.
- the indexing hinges according to the present invention are placed at the top and bottom of the door and therefore have to be secured to supporting structure above and below the door. It is to be understood, however, that the indexing hinge according to the present invention is not necessarily limited in those ways.
- FIG. 1 shows top and bottom hinges 10 mounted respectively to the soffit or overhead defining the top of the opening into a shower (reference number 12) and the stoop or bottom defining the bottom of the opening into the shower (reference number 14).
- Each hinge is secured to the top and bottom of shower door 16 but near to the left side 18 of door 16, is viewed in FIG. 1.
- Door 16 pivots about a pivot axis that extends through hinges 10.
- a handle 19 on the opposite side of door 16 can optionally be used to open and close door 16.
- the vertical pivot axis through hinges 10 allows door 16 to be pivoted around that vertical pivot axis between a closed position (as shown in FIG. 1), and open positions.
- the opening to the shower may or may not have a sill, jamb or stop to limit the pivotal movement of door 16. Therefore, without such a blocking structure, door 16 could pivot or open both outwardly and inwardly with the only limit being the structure adjacent edge 18 of door 16, if door 16 is rotated almost 360° in either direction.
- FIG. 2 illustrates, in enlarged fashion, a hinge 10. Because both top and bottom hinges 10 are identical in structure, only one will be discussed herein. The opposite hinge 10 simply needs to be reversed in orientation as is shown in FIG. 1.
- Hinge 10 comprises what will be called tram body 20 as a mounting member to the supporting structure defining the opening to the shower. Screws 22 can be placed through apertures 24 in flanges 26 of tram body 20 to mount tram body 20 to a soffit, stoop, or other structure defining the opening to the shower. Such structure can include overheads, sidelights, floors, walls, or any supporting structure. Other mounting hardware could be used such as is well within the skill of those skilled in the art.
- the glass shower door is gripped by a clamp comprising what is called pivot body 30 and a cover plate 32. As will be discussed in more detail later, each of members 30 and 32 has a recess which includes a gasket 34 to grip the sides of the glass shower door.
- Cover plate 32 has apertures 36 into which screws 38 pass and mate into threaded apertures in pivot body 30. Cover plate 32 and pivot body 30 can then be brought together to provide a clamping action on opposite exterior sides of door 16. Reference can be taken to application Ser. No. 08/319,468 regarding the details of this clamping action. In a preferred embodiment, particular cutouts 28 in the margin of door 16 (see FIG. 12) at the location of pivot body 30 are made to assist in secure mounting of hinge 10 to glass door 16.
- a pivot pin has one end which is fixed in pivot body 30.
- the opposite end of the pivot pin (not shown in FIG. 2, but see FIGS. 3-5) extends into tram body 20 where it is rotatably journaled.
- a pivot axis indicated generally at 40 in FIG. 2 is then defined.
- the configuration of the pivot pin and tram body 20 is such that upon rotation of pivot body 30 (and cover plate 32), the pivot pin rotates in tram body 20 but pivot body cover plate 30/32 cannot be separated from tram body 20.
- FIGS. 3 and 4 show generally how hinge 10 allows pivoting movement of door 16.
- tram body 20 is fixed from movement by its attachment to the soffit or overhang. It includes an aperture 44 in which a main pivot pin 42 is rotatably journaled.
- Pivot pin 42 extends downwardly (FIG. 3 is a top sectional view looking downward) to pivot body 30 where it is fixedly secured. Therefore, as is shown in dashed lines at 16A and 16B in FIG. 3, door 16 can move away from the position in solid lines in either direction (see arrow 46).
- hinge 10 is attached to door 16 in the position shown in FIG. 1, near side 18 of door 16.
- door 16 pivots about its one side defined by side 18.
- FIG. 4 shows how hinge 10 could be placed at or near the center top and bottom of door 16, (with appropriate cutouts 28 as indicated at FIG. 12).
- Tram body 20 would be fixed to the soffit or overhang at or near the center of the opening to the shower and likewise the second tram body 20 secured to the center of the stoop or bottom of the opening to the shower.
- Pivot body 30 and cover plate 32 would clamp door 16 at or near its top and bottom center and pivot pin 42 would be appropriately assembled.
- the pivot axis for the door would essentially be down its center.
- door 16 can potentially pivot in either direction but such pivoting would be down a vertical and central pivot axis. This is sometimes desired.
- Door 16 if no mechanical stops existed around its perimeter, could rotate 360° or more in either direction.
- FIG. 5 illustrates all the parts of hinge 10 in exploded fashion.
- Tram body 20 includes pivot pin aperture 44 which extends from an opening end 43 into an enlarged hollow 45.
- the ghost lines of FIG. 5 illustrate portions 43, 44, and 45.
- Main pivot pin 42 has a first end 52 that is slightly smaller in diameter than the inside diameter of pivot pin aperture 44.
- a second end 54 of main pivot pin 42 has a larger diameter than first end 52.
- End 54 also contains longitudinal detents 56 and 58.
- the diameter of opposing concave walls 60 on opposite sides of hollow 45 are slightly bigger in diameter than the diameter of end 54 of main pivot pin 42 and receive end 54. Because end 54 is larger in diameter than pivot pin aperture 44, main pivot pin 42, when assembled, results in its end 52 being rotatably journaled in pivot pin aperture 44 but with the outermost portion of end 52 extending through and outside of portion 43. End 54 of main pivot pin 42 is rotatably journaled in opposing concave walls 60 but cannot move into pivot pin aperture 44 because aperture 44 is smaller than end 54 of pivot pin 42.
- Biasing members are installed in tram body 20 on opposite sides of end 54 of main pivot pin 42, when installed, to provide indexing for hinge 10.
- each biasing member comprises a sub roller pin 62 of metal, force fit into a complimentary groove 64 in the concave face 66 of spring guide 68.
- a spring 70 has one end which enters cutouts 72 in the portion of spring guide 68 opposite concave face 66.
- biasing member combination spring guide 68, sub roller pin 62, and spring 70
- spring guide 68, sub roller pin 62, and spring 70 on each side of end 54 of main pivot pin 42.
- the combination of both biasing members and main pivot pin 42 are placed into hollow 45 by compressing springs 70 while spring guides 68 are against end 54 of main pivot pin 42.
- hollow 45 includes opposite end walls 74 which serve as fixed walls of abutment with opposite springs 70.
- base cover 76 is inserted over large hollow 45.
- enlarged portions 78 on opposite sides of end walls 74 of hollow 45 receive legs 80 of base cover 76 to assist in positioning and holding base cover 76 in position.
- the perimeter of base cover 76 follows the outline of hollow 45.
- main pivot pin 42 cannot move out of tram body 20 in any direction. It can rotate about axis 40 (see FIG. 2). See FIG. 13, a cross-sectional view of assembled hinge 10 to more clearly see the relationship of parts of hinge 10.
- FIG. 5 also shows pivot body 30 has a main portion 82 and a clamping portion 84.
- Main portion 82 includes a top surface 85, a depression 86, and a concave cutout 88.
- a clamp block 90 has perimeter dimensions to fit within depression 86 and be secured in position by bolts 94 through apertures 96.
- Clamp block 90 also includes a concave cutout 92 which lines up with concave cutout 88 of main portion 82.
- Cover plate 32 also includes a gasket (not shown in FIG. 5) like gasket 34 of pivot body 30.
- Top surface 84 of main portion 82 of pivot body 30 includes threaded apertures 98 to receive screws 38 to clamp cover plate 32 to pivot body 30.
- Final assembly of the total hinge 10 includes positioning the outermost portion of end 52 of main pivot pin 42 (extending out of tram body 20) into cutout 88 of pivot body 30 and then securing clamp block 90 over end 54 of main pivot pin 42.
- End 54 includes knurls or longitudinal cuts 99.
- Concave cutout 92 of clamp block 90 is of a smaller circular diameter than the diameter of end 54 of main pivot pin 42.
- the edges 93 on both sides of concave cutout 92 corporate with longitudinal cuts 99 to secure end 54 of main pivot pin 42 in pivot body 30 and hold it against rotation while clamped by clamp block 90.
- a support bearing 100 has a first end 102 that is received and mates into pivot pin aperture 44 in tram body 20.
- the second end 104 of bearing 100 is cone shaped and larger in diameter than first end 102 and matingly fits into the cone shaped void 43 in tram body 20.
- the outer end surface 106 of bearing 100 being flat, includes two pins 108 which mate into holes 110 in portion 82 of pivot body 30 (see FIG. 13).
- end 52 of main pivot pin 42 passes closely through the hollow channel 112 in support bearing 100 and is clamped by clamp block 90 into concave cutout 88 pivot body 30.
- Support bearing 100 is fixed from rotation by pins 108 in holes 110, and abuts but separates pivot body 30 from tram body 20 and provides a bearing surface 114 between the adjacent surface of tram body 20 (in void 43) (see FIG. 13).
- Tram body 20 will be fixed to a wall.
- Bearing 100 is fixed to pivot body 39. Thus pivoting of pivot body 30 will cause pivot bearing 100 to rotate in void 43 of tram body 20.
- FIGS. 6-8 illustrate the operation of hinge 10.
- FIG. 6 shows, in sectional view, the assembled indexing hinge 10.
- FIG. 6 is a view looking down on top of end 54 of main pivot pin 42.
- Pivot pin 42 has a rotational position such that detents 56 and 58 align with sub roller pins 62.
- each spring 70 push against a wall 74 and thus bias spring guides 68 towards pivot pin 42. This in turn biases sub roller pins 62 against the perimeter of end 54 of main pivot pin 42.
- sub roller pins 62 are larger than the distance across detents 56 and 58, but is small enough so that a portion of sub roller pin 62 enter detents 56 and 58. By this manner, when door 16 is in the position shown in FIG. 6, it is indexed. By indexing it is meant that the entry of sub roller pins 62 into detents 56 and 58 tends to hold door 16 against rotation.
- FIG. 7 shows door 16 rotated from the position of FIG. 6. Because end 54 of pivot pin 42 is clamped to pivot body 30. Pivot pin 42 rotates with the pivoting of door 16. Therefore, if sufficient force is applied to door 16 to overcome the forces of sub roller pins 62 biased into detents 56 and 58, end 54 of main pivot pin 42 will rotate out of alignment with sub roller pins 62. Springs 70 will continue to bias sub roller pins 62 against the perimeter of end 54 of main pivot pin 42, but since sub roller pins 62 are not in detents, there is no indexing or tendency to hold door 16 from rotation. Sub roller pins 62 would follow the smooth convex portions of end 54 of pivot pin 42 between detents 56 and 58, and not impede rotation of door 16.
- FIG. 8 shows in enlarged detail the relationship of detents 56 and 58 to sub roller pins 62 when door 16 is rotated from the indexed position.
- FIG. 9 illustrates certain dimensional characteristics of main pivot pin 42 according to the preferred embodiment described herein.
- Main pivot pin 42 is 1.456 inches in total length, with first end 52 being 1.081 inches in length.

- Countersunk void 43 widens at a 45 degree angle from 0.406 inch to 0.75 inch diameter to receive end 102 of bearing 100 and bearing surface 114 of the second end 104 of support bearing 100.
- Bore 112 through bearing 100 is 0.320 inches in diameter.
- Support bearing 100 is made of nylon 6-6 and has a 0.396 inch outside diameter.
- Surface 114 is 135 degrees from the sidewall of end 102 of bearing 100.
- the distance between opposite end surfaces of bearing 100 is 0.456 inches, the length of first end 102 is 0.231 inches.
- the distance from the end of first end 102 to the end of bearing surface 114 is 0.366 inches.
- the height of pins 108 is 0.125 inches and their diameter is 0.125 inches. They are spaced apart linearly 0.375 inches.
- Pivot body 30 is made of brass 3600. Flanges 26 are 0.2 inches thick with the recesses for gaskets being 0.055 inches (also see FIG. 5).
- portion 82 The longest dimension of portion 82 is 2.0 inches and its width is 0.75 inches. Depression 86 is 0.144 inch deep and concave cutout 88 has a radius of 0.156 inch compared to the 0.141 inch radius of concave cutout 92 of clamp block 90.
- Cover plate 32 is made of brass 3600, has a thickness of 0.200 inch with recess depth of 0.055 inches for the gasket 34 which is 3/32" thick.
- Cutouts 28 in door 16 to receive portion 82 of pivot body 30 are 23/16 inches long and 17/16 inches in depth from the edge of door 16. Corners are cut at a radius of 5/16 inch to correspond to the rounded corners on pivot body 30.
- Clamp block 90 is made of brass 377 and has outside dimensions of 0.990 inch long and 0.750 wide. It is 0.200 inch thick with the 0.155 inch radius for concave cutout 92. It can also have a slight depression of approximately 0.015 inches on either side and including concave cutout 92.
- Gasket 34 are neoprene 3/32 inches 85 Duro Neoprene in a C-shape. They are 3.255 inches long and 1.880 inches wide. Each leg of the C-shape is 0.568 inches wide. The interior of the C-shape is 1.315 inches by 2.120 inches with a radius of 0.25 inches curved interior corners. The exterior curved corners are 0.125 inch radius.
- Base cover 76 is nylon 6-6 having a total overall length of 1.640 inches and a thickness of 0.058 inches.
- the height of legs 80 is 0.433 inches.
- FIG. 9 illustrates the use of two detents 56 and 58 for main pivot pin 42.
- two sub roller pins 62 and two detents 56 and 58 simultaneously work to hold the door in the indexed position.
- one detent and one sub roller pin could be used.
- more than two sub roller pins 62 and detents could be used.
- the precise shape of the detents can vary (see e.g. 56B and 58B FIG. 11).
- sub roller pin 62 when in a detent, abuts at two points on opposite sides of the detent.
- FIGS. 10 and 11 illustrate that the detents do not have to be at 90 degrees to one another. If multiple indexing positions are desired, one or more detents can be placed at other than 90 degrees to one another. If, for example, an indexed position at 45 degrees was desired, the detent would simply have to be formed at the appropriate position. Any angle is possible. This further highlights that if an indexing position different from an original indexing position is desired, pin 42 would merely have to be changed rather than the entire hinge.
- hinge 10 is adjustable after tram body 20 has been installed. As previously mentioned, if, for example, mounting holes for tram body 20 are drilled into a supporting wall but are not perfectly aligned with the plane of the opening to the shower, tram body 20 can still be installed into those drilled holes and the proper indexing can work. Therefore, even though the relationship between the detents in pin 42 and the sub roller pins 62 is fixed when tram body 20 and pivot pin 42 are assembled, end 52 of main pivot pin 42 can be placed into concave cutout 88 in pivot body 30, the door adjusted to the desired indexed position, and then clamp block 90 secured to pivot body 32 to fix the orientation of door 16 to hinge 10. Thus, by aligning the detents 56 and 58 with sub roller pin 62 when mounting tram body 20, the installer can compensate for any misalignment in installation of tram body 20 by this method.
- indexing hinge 10 can be used either at the top and bottom and towards the either side of door 16, or towards the middle of the top and bottom of door 16. In fact, any locations along the top and bottom of door 16 are possible. By appropriate modifications, hinges 10 can also be used along either vertical side of door 16.
- clamp block 90 could include a protrusion 150 (FIG. 14) that includes an aperture 151 therethrough.
